Cartoon representation of ADP-FtsH (Top) and apo-FtsH (Bottom) with view onto AAA ring (Left), side (Middle) and protease (Right). The protease ring is shown in red and the AAA ring in magenta and green. Zinc ions are displayed as cyan spheres, the pore residues Phe-234 in yellow space-filling mode. Carbon atoms of ADP and TAPI are shown in gray. (A) ADP-bound state, the AAA ring has C2 symmetry. (B) Apo-state, the AAA ring has C6 symmetry.
